Abstract
Thaumatocaryon is a small genus of South American Boraginaceae with only three accepted names. This genus, along with Moritzia, comprises a monophyletic lineage called Moritziinae. During a review of herbarium specimens, we found morphological divergences that led us to conclude that Thaumatocaryon is more complex than previously known. According to the morphologic analysis, we recognize nine species, resulting from the revalidation of T. hilarii and the description of five new species. The species are differentiated by characteristics such as phyllotaxy, indumentum, as well as the length and color of the corolla, the morphology of stems and basal leaves, and the arrangement of flowering stems. We present a detailed description of each species, updating the four previously described species, field photographs (when available), exsiccate plates, distribution maps, and a key for all species of the genus.
Tetracera is the only genus within Dilleniaceae with a pantropical distribution. During efforts for a taxonomic revision of the neotropical species, we identified incongruences between application of names and their taxonomic identities, based on protologue and type specimen analysis. Here we describe a new species for...

Recent morphological and phylogenetic studies highlighted the paraphyly of Cyrtorchis sect. Homocolleticon, in which Cyrtorchis ringens sensu lato constitutes a polyphyletic species complex. In this complex, three morphogroups were distinguished, representing putative new taxa. Here, we describe one of these new taxa b...

Three new species of sun orchid (Thelymitra) endemic to Aotearoa New Zealand are here described: T. palustris, T. scabrifolia and T. semaphora. The morphological distinctiveness of these three species has been acknowledged for decades; however, their taxonomic status has remained unresolved. Evidence from existing kary...

Stachybotryaceae (Hypocreales, Sordariomycetes) is a genus-rich, highly diverse family with a worldwide distribution across terrestrial and aquatic habitats. Hyalinostachys is a monotypic genus, with its type species, H. cylindrospora, isolated from bamboo. In this study, two fungal isolates were collected from decayin...
